The CBS Building in New York City is known as Black Rock. The building houses CBS Corp. headquarters. The building, was designed by Eero Saarinen (obviously) and opened March 24th, 1965 –four years after Saarinen’s death. The building is 38 stories tall and is over 872,000 square feet.
The building was a collaboration between Saarinen and CBS president at the time, Frank Stanton. The building is called the Black Rock due to the dark granite skin of the building and the large pillars. The building was the first (and one of the only) skyscrapers with a reinforced concrete frame designed by Mario Salvador. Granite covers the concrete frame and Salvador and Saarienen created a unique skyscraper, at the time, whose pillars were more dominant then its windows.
The Black Rock only skyscraper ever designed by Eero Saarinen. Like many of his other buildings, Saarinen did not live to see the completion of his building due to his sudden death in 1961, leaving many projects in the middle of construction.
This building is considered one of the three gifts Saarinen gave to New York. The two others being the TWA Terminal at the John F. Kennedy airport and the Vivian Beaumont Theatre.
